NASA’s James Webb Telescope (JWST) has made a surprising discovery at the edge of our universe that astronomers say should not exist. Images were taken of three 12.8 billion-year-old “Red Monster” galaxies, a billion years older than the Big Bang and roughly the size of the Milky Way.
Astronomers have suggested that star formation and thus galaxy growth in the early Universe was much more efficient than previously thought, prompting experts to rethink current models of galaxy formation. The researchers noted that according to the Lambda Cold Dark Matter (LCDM) model, the most widely accepted cosmological model, these “Red Monster” galaxies should not exist.
LCDM argues that the first galaxies formed in the Universe did not have enough time to become as large as these newly discovered objects appear to be. “The discovery of three such massive monsters presents a fascinating mystery,” Stein Wuyts, one of the study’s authors and the Hiroko Sherwin Chair in Extragalactic Astronomy at the University of Bath, said in the Daily Mail.
By the way, this isn’t the first time JWST has discovered “incredibly massive” ancient galaxies. These three are just the latest in a series of discoveries that have caused astronomers to question their understanding of how early galaxies formed.
Researchers call the three latest objects “Red Monsters” because of their massive size and high dust content, which gives them a distinctive red color in telescope images.
